Veni Creator Spiritus is a traditional Christian hymn believed to have been written by Rabanus Maurus, a ninth-century German monk, teacher, archbishop, and saint. When the original Latin text is used, it is normally sung to a Gregorian Chant tune first known from Kempten Abbey around the year 1000. The hymn has been translated and paraphrased into several languages, and adapted into many musical forms, often as a hymn for Pentecost or for other occasions that focus on the Holy Spirit.

Rabanus Maurus Magnentius, also known as Hrabanus or Rhabanus, was a Frankish Benedictine monk, theologian, poet, encyclopedist and military writer who became archbishop of Mainz in East Francia. He was the author of the encyclopaedia De rerum naturis. He also wrote treatises on education and grammar and commentaries on the Bible. He was one of the most prominent teachers and writers of the Carolingian age, and was called "Praeceptor Germaniae", or "the teacher of Germany". In the most recent edition of the Roman Martyrology, his feast is given as 4 February and he is qualified as a Saint ('sanctus').
